Next-generation wireless networks are expected to be highly heterogeneous, multilayered,
with embedded intelligence at both the core and edge of the network. In such a context …

We consider a cellular network deployment where UAV-to-UAV (U2U) transmit-receive pairs
share the same spectrum with the uplink (UL) of cellular ground users (GUEs). For this …

Abstract Device-to-device (D2D) communication is expected to play a significant role in
upcoming cellular networks as it promises ultra-low latency for communication among users …

Direct communication between two or more devices without the intervention of a base
station, known as device-to-device (D2D) communication, is a promising way to improve …

Device-to-device (D2D) communication enables the user equipments (UEs) located in close
proximity to bypass the cellular base stations (BSs) and directly connect to each other, and …
